Die Erfindung betrifft einen Boxapparat, bestehend aus einem an Federn befestigten Ball, welche in Schraubzwingen angeschraubt werden. Den bestehenden Boxbällen gegenüber zeichnet er sich besonders dadurch aus, daß er sich an allerhand Gegenständen, wie Türrahmen, Tischen usw., leicht anbringen läßt und bei seiner Abnahme keine Spuren hinterläßt. Sein Zweck ist, die Stoß- und Schlagkraft des mit ihm Übenden auszubilden. Auch kann er als kleiner Übungsball (Abb. ι) zum Üben der Treffsicherheit am Tisch usw. angeschraubt werden.The invention relates to a boxing apparatus consisting of a box attached to springs Ball, which are screwed into screw clamps. Opposite the existing boxing balls it is particularly characterized by the fact that it can be used on all kinds of objects, such as door frames, Tables, etc., can be easily attached and leaves no traces when removed. Its purpose is to develop the impact and impact strength of those who practice with it. It can also be used as a small exercise ball (Fig. Ι) for practicing accuracy at the table, etc. be screwed on.

Auf der Zeichnung ist die Erfindung in zwei Ausführungen dargestellt. Abb. ι ist Außenansicht und Abb. 2 ein Querschnitt. [In the drawing, the invention is shown in two versions. Fig. Ι is an exterior view and Fig. 2 is a cross section. [

Nach Abb. 1 ist die Feder aus einem Stück konischen Stahles mit mehreren Windungsao gruppen — zur größeren Stabilität und Biegefähigkeit — dargestellt. Nach Abb. 2 besteht j die Feder e aus zwei Teilen, welche durch das mit Überwurfmuttern m und auf den Federn befestigten Ringen Z gesicherte Verbindungsstück d oder auch auf andere Art zusammengehalten werden. Es sind noch andere Federn verwendbar, z. B. eine einzige lange Feder, deren eine Windungsgruppe, wie auch die Windungen der übrigen Federn, auf'einer an der Schraubzwinge k angebrachten Platte i flach aufliegt. Der Ball wird, wie Abb. 2 zeigt, derart befestigt, daß die Feder c. mit dem an ihr befindlichen Flügel r, der Feder υ ; und der Walze η in die Hülse Ii eingeschoben wird, und zwar so weit, daß der Flügel r am i anderen Ende herausragt, wobei die Feder ο zusammengedrückt wird. Nach einer Vierteldrehung des Balles schnappt der Flügel r in j die kurzen Nuten qu ein, und der Ball wird durch j die Druckfeder 0 in dieser Stellung gehalten. ^! According to Fig. 1, the spring is made of a piece of conical steel with several Windungsao groups - for greater stability and flexibility - shown. According to Fig. 2, the spring e consists of two parts, which are held together by the connecting piece d secured with union nuts m and rings Z attached to the springs, or else in some other way. Other springs can also be used, e.g. B. a single long spring, one winding group of which, like the windings of the other springs, rests flat on a plate i attached to the screw clamp k . As shown in Fig. 2, the ball is fastened in such a way that the spring c. with the wing r on it, the spring υ ; and the roller η is pushed into the sleeve Ii , to the extent that the wing r protrudes at the other end, the spring ο being compressed. After a quarter turn of the ball, the wing r snaps into j the short grooves qu , and the ball is held in this position by the compression spring 0. ^!

Claims

Patent Claims: j

ι. Boxing exercise ball which is filled with air and slipped onto its holder i with a sleeve penetrating it, characterized in that the push-on sleeve, cooperating with a resilient locking device of its wearer, holds the ball on the holder (e) carried by a screw clamp and is allows immediate removal and putting on.

2, boxing exercise ball according to claim 1, characterized in that the sleeve (/;) sits in an airtight rubber hose penetrating the rubber bladder of the ball and a downwardly widened bore for receiving the compression spring (0) and the roller (w) on the resilient support (Y) and has four grooves (qu) at its upper end, two of which go through to the widening of the bore in order to allow the passage of the wing (r) on the tongue (e) , while the other two grooves are only approximately 1 ¹ J reach ₀ cm deep into the sleeve to snap the wing (r) into place after a quarter turn of the spring - and to prevent the ball from flying off by pressing the compression spring (0), supported on the spring ( Y) located roller («), the sleeve (Λ) and with it presses the ball against the wing (r).

3. Boxing exercise ball according to claim 1 and 2, characterized in that the suspension spring (e) of the ball is provided with different turns, the lowest of which rests flat in a circle on a plate (/) which is located on the screw clamp (k) , and in that the wing (V) and the roller (s) with the compression spring (0) are located at the upper extended end of the spring (e).

4. Boxing exercise ball according to claim 1 to 3, characterized in that the suspension spring (e) consists of two pieces (strong at the bottom and weaker at the top), both of which are held together with a connecting piece ((/) - or in some other way - in which two threads are cut into which the two springs are screwed and secured by rings (Z) and union nuts (m) with opposing threads in order to prevent the spring from automatically unscrewing when swinging.

5. Boxing exercise ball according to claim 1 to 4, characterized in that the spring (e) is wound from a piece of conical steel in such a way that it has different groups of turns (Fig. 1).
